Floor sweeping apparatus (9) of the type having a rotary brush member (20), which in use is driven to rotate about a generally horizontal axis, the brush member (20) having bristle elements (22) that, as the brush member (20) rotates, extend during part of their range of movement through an aperture (13) in a base plate (12) of a housing (10) in which the rotary brush member (20) is rotatably journalled has at least one bristle element (22), hereinafter called an end-most bristle element (25), arranged immediately adjacent to each end of said brush member (20), and a deflector member (26) is provided at each end of the aperture (13) to co-operate with said end-most bristle element (25) at the respective end of the brush member (20). The deflector members (26) deflect said end-most bristle elements (25) axially beyond the end of the aperture (13) as said end-most bristle elements (25) extend through the aperture (13) during the rotation of the brush member (20) to effectively extend the sweeping action at least up to, and preferably beyond, the outer edge of the housing.
Floor sweeping apparatus comprising a housing having a base plate, and a rotary brush member rotatably journalled in the housing, wherein the brush member is driven to rotate about a generally horizontal axis, the brush member having bristle elements that, as the member rotates, extend during part of their range of movement through an aperture in the base plate, wherein there is at least one bristle element, hereinafter called an end-most bristle element, arranged immediately adjacent to each end of said brush member, and wherein a deflector member is provided at each end of the aperture to co-operate with said end-most bristle element at the respective end of the brush member to deflect said end-most bristle element outwardly away from the brush member in the axial direction with respect to the generally horizontal axis as said end-most bristle element extends through the aperture during the rotation of the brush member.
